MOTOR-VEHICLE.

Specification of Letters Patent.

Application filed May-1'7, 1915. Serial N 0. 28,608.

To all whom it may concern:

Be it known that I, J ULES GOBIET, a citizen of the rench Republic, and residing at Valentigney, Doubs, France, have invented certain. new and useful Motor-Vehicles and the like, of which the following is a specification.

The arrangement forming the subject matter of the present invention is intended to .allow the suspension of a motor vehicle the propulsion of which is obtained by means of an endless metal chain resting on the ground, this chain being of special construction and movement being imparted to it by a sprocket wheel, the shaft ofwhich forms part of the suspended portion'of the machine. One form of carrying the invention into effect. is shown by way of example in the accompanying drawings, in which:

Figure 1 is a view in elevation of a machine provided with the new arrangement, the part of, the machine lying in front of the said arrangement having been taken away to show the details ofassembling.

Fig. 2 is a partial plan view of the suspension and driving means, and

Fig. 3 is a front .view of the means represented in Fig. 2.

1 is one of the longitudinal members of a principal chassis carrying the motor and the various transmission and driving parts, as in an ordinary motor driven Vehicle.

The longitudinal members 1 ,are transversely connected by two cross members 2 which in their turn carry two small longitudinal members 3 perpendicular to these cross members, and disposed parallel and below the principal longitudinal members.

On the cross members 2 there are fiXed two guides 4 which consist of angle irons. These angle irons receive between them a block 5 which can undergo displacement as in a guide path. Each vof thetwo blocks 5 is pierced with a-hole in which engages a pivot 6 fixedly mounted on'a' cross member 7- belonging to asecondary chassis formed by two cross members 7 and two longitudinal members 8. v p

The two longitudinal members 8 carry two guides 9 similar to the guides 41, each of which receives a sliding block 10 forming a slide as in the method of mounting described for the blocks 5. The two blocks 10 are pierced with a hole in which engages a member 3 of the p The rollers 14 steel they longitudinal principal chassis.

It will be understood thatthe whole of this assembling arrangement behaves in the manner of a Cardan joint, when the principal chassis is carried by the secondary chassis by the agency of springs 12 spiral or of other suitable form. Blocks'5and 10 are the jointing points of this large Oardan joint; they allow of the free play of the springs 12, but they oppose all longitudinal or transverse displacement of the principal chassis relatively to the secpn'dary chassis. The whole, therefore, constitutes an elastic suspension and a thrust arrangement of the principal chassis carrying the driving parts. a

The longitudinal member 8 carries journals 13 on which are mounted carrier rollers 14 which run on the chain 15 and support the upper side of the latter.

The chain 15 is driven by a sprocket 16 revolving on a shaft fixed to the principal pivot 11, fixed to the sinall chassis.

It results from this that the rollers 14 Patented Feb. 20,1917.

are in elastic relation with the sprocket 16 through the medium of the chain 15 and owing to the fact of the/special joint of the secondary chassis beneath the principal chassis;

run on the cheeks 17 of the lower side of the chain and also carry its I upper side.

A tightening pulley 18, located toward the front of-the vehicle and connected to the principal chassis by a stretcher, serves'to maintain a suitable tightness for the chain 15.

To effect turns, it suflices to put the brake on one of the two sprocket wheels 16 which actuate each of the two chains. One can thus turn tothe right or the left according.

to the side of'the braked sprocket wheel.

-The propelling chain is fitted with a set of plates 19 the special rounded form-0f,

which These plates are preferably are connected to the chain proper by bolts which traverse them and form at the same time stays on which the chain rollers are strung.

20 is a speed gear case intended 'both'to drive the chain'sprocket 16 and the tools of a plowing-apparatus which can be connected to either of the two chassis.

is intended to facilitate turning.'

of stamped I claim as new anddesire to secure by the various transmission now described myinvention what Let- Having ters Patent is 1. In a motor driven agricultural Vehicle,

a principal chassis carrying the motor and and driving parts in combination with an auxiliary chassis, vertically sliding universal ]01Ill means between'said two chassis which do not allow of I a principal chassis carrying relative longitudinal or lateral displacement,

and flexible supports by which one chassis is carried by the other.

2.- In a motor driven agricultural vehicle,
